The nose of this shaft (where it slides into the roller bearing) measures .875" in diameter. I think this is a TR-4 mainshaft, but it could be a TR-6. I think the TR-6 mainshaft nose was slightly smaller in diameter than the TR-4, but I can't remember the diameters of each. Can someone help me identifies which this is?</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Second item is a rear axle shaft. It measures 25" long. First, is it from a TR-3 or TR-4 rear axle? I know that the two axle shafts in a unit were different lengths. In whichever axle this goes (TR-3 or TR-4) is it the short one or the long one?</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Again, many thanks.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Jack<br></div></div></body></html>
